The FC1000 Optical Frequency Combs a compact and flexible fiber-based frequency comb system for direct measurement of absolute optical frequencies. Thelaser operation relies on the figure 9® mode locking technology, which ensures
excellent stability and low-noise operation. The femtosecond laser is ready to use
at the press of a single button, and automatic phase lock loops ensure easy stabilization to either a RF or an optical reference. Due to the mature system design
including several motorized actuators, our customers report long-term operation
where the comb is phase locked over weeks. With a wide range of optional addons, we tailor individual systems to customer specific requirements. With the optional ASTRO Extension Package the system offers high mode spacing. Spectral
broadening and flattening stages generate the output in the user-defined, visible
wavelength range (e.g. 450-700 nm)

Optical Frequency CombCOMPLETE SOLUTIONS:The optical frequency comb is a complete system including mode locked Yb-doped fiber laser with PM output, that is spectrally broadened
to generate the octave-spanning spectrum, and an f:2f interferometer. The The turn-key, fully hands-off optical setup offers compactness inan extremely robust design and features 24/7 operation with remote access to measured data. A separate rack cabinet houses control units,
phase-locked-loops, data acquisition, and displays.
